Title: Process and apparatus for the manufacture of a heat-insulated metal pipe
IPC: B29C48/151
Filed: 1980-11-03
Abstract: A metal pipe (2) is heat insulated by a surrounding seamless extruded PVC foam jacket (3) having internal webs (4) at which it is supported on and bonded to the pipe (2). The pipe (2) is heated prior to passage through an extrusion die (9) to a temperature which is sufficiently high to provide adequate bond between the pipe (2) and the PVC jacket (3) to counteract the tendency of the PVC to lift by expansion from the pipe after leaving the extrusion die but which is not so high that adhesion is lowered beyond the expansion force of the foaming jacket due to a lowering of the viscosity of the melt bond. The plasticised PVC is heated in the extruder and mixed with a foaming gas. The plasticised PVC melt is applied to the pipe whilst in the extrusion die and in order to assist in adhesion between the PVC and the pipe they are both moved with the same velocity in the bonding zone. The webs (4) are shaped by pins (13) which extend downstream from the extrusion die mandrel to a location (15). <IMAGE>
